PLOW.

Specification of Letters Patent.

Patented June 18. 1912.

Application filed December 9, 1910. Serial No. 598,534.

- sometimes called disk plows and sometimes the registering holes, and as the lin rotary plows.

My plow is especially designed for deep plowing; and the objects are, to provide such plow -with means for steering it prop erly, means for plowmg one or two furrows at a time, and means for increasin the depth and width of the furrow plowe In the accompanying drawing, Figure 1 is a top or plan view of a plow embodying my invention. Fig. 2 is a side elevation of the rear caster and the bracket holding it. Fig.

'3 is a side elevation of the rear disk and its journal and supporting plate thereof renioved from the bracket shown in Fig. 2.

Referring to the drawing by reference numerals, 1, 1, l 1", 1, and 1 designate the frame of the plow or plowing machine, as it may also be termed. Y

2 is t e draft clevis of same and is at-' tat-lied i a perforated fiat transverse bar 3, secured at the front end of the frame.

4, 5 and 6 are the SUPPUlllIlg wheels of the frame. These wheels, and the usual lever mechanism (not shown) by which they are inclined, or the frame raised and lowered, are so well known that I need not here show or further describe the same. Only this may be said in regard to the front wheel 4, that the stem 7 of the short axle 8 is provided with a horizontal forward arm 9, which is pivotally connected at 10 with the rearward arm 11 of a bell-crank lever 11-'-12, which is fulcrnmvd at 13 upon the outer end of a link-bar 14; the latter is provided with a series of holes 15,'either of which may be brought directly over one of the holes 16 in the draftclevis 2 and a pin 17 dropped into -bar and the bell-crank lover may thereby be held more or less toward the right or left side of the plow, the' arm 9 is thereby caused to hold the wheel 4 in any required direction for steering the plow. Said connection with the draft clevis will also cause the wheel 4 to retain its position relative to the direction in which the draft animals, or other power pull at the clevis 2.

To enable the driver to change the direction of the wheel 1,- temporarily or otherwise, while the machine is in motion, the arm 12 of the bell-crank lever is b a rod 18 connec'ted with an upright han -lever 19, which is fulcrumed ,on a bracket 20, that is secured on the frame and has a toothed Sector 21 engaged by a dog 22, the latter being carried by the lever.

When the ground operated on and other condltions remain unchanged for a conslderable length of time, the link-bar 14 may have its inner end removed from the clevis and secured upon the transverse bar 3 by placing the pin 17 as 17 in Fig.1.

23 is a rocker arm fixed onthe shaft 2t and connected with an operating lever (not I shown) which causes said shaft to turn and by its crank-shaped portion 25 raise and 75 lower the frame. Other means for the same. purpose is not shown, as already before stated.

Onthe arm 1 of the frame is mounted by a bracket 26 a rotatable disk 27; and in di' rect line rearward therefrom is mounted on the frame arm 1 a similar' disk 28; The mounting of the latter 'disk involves a curved or segmental perforated plate 29, on which the journal bearing 30 of the disk is formed; and a similarly curved bracket plate 31, which is secured to the frame by bolts 32 and is rovided with several, preferably tapped, iioles 33 for the reception of either bolts or screws 34, which are passed into said plate through two or more of the holes 35 in the plate 29 (see Figs. 2 and 3); the holes selected depending on the depth and width it is desired to have the disk operate in the soil; the vertical position or height of the plate controlling the depth, and the rearward moving of the plate enlarging the width of the furrow by giving the disk 0.

-bracket 31 is also journalecl the stem-36 of,

the caster 6; said stem may have collars 37 with set-screws 38 to make the st em adjustable up and down in the bracket, or means (not shown) may be provided for raising and lowering the frame on the stem by a lever and toothed sector of the well know types used in similar machines.

39 designates the beam of a common mold-hoard plow, which it is unnecessary to show in detail; said beam is secured upon the rear portion of the frame by bolts 41 passed through the beam and through clamps 40 taking underneath the frame,said

'c'orner'of the frame'to the arm 1.-l of the frame, as a brace, to stiffen the latter, so' that it may notneecl to be extra heavy" although it is Iong'and' exposed to mu'h st-rain from the'rear disk, :orsaid-disk afid' the mold-board plow. V

In the operation of the plow, the plowing is'usual'ly performed .by twoldisks, 27 and 28, which are mounted to rotate' on the frame'jone in: rear of f'th'e other, the real one at a greater depth than the front one, so as to deepen the furrow made bythe front disk; 'thi's beingdesir'able where the land is much woi'n vout, or in the so-called dry farming, where extra depth is necessary to reach fresh soil, or moisture, as the. casei maybe. And by setting the rear'disk at an \extra' obtuseangle to a straight forward line, the furrow will also be wider and thus ,madeeasier for the right side horse that has ftoti-atel in it during the plowing of the next furrow in the same manner While.

suchplowing going on the' moldfboard' plow will m'ake a 'shallow furrow fonthe' disks to follow during the next operation,

such shallow furrow. enabling the disks to work deeper than if nomold-boa'rd plow-v was used. In-plowing i dinary' land the" 'rear disk '28 may be"eitherjremoved or d tolthe position shown dottedlines, H oviiig'ttfebracketplat 31 and its bolts 32'a1id rear caster with it. When the rear diskis in said'forward position, the moldboard plow is removed. from the frame and the two disks are plowing in one operation two complete furrows of common depth;

or; if a little extra .depthis desiredthe rear disk maylbe regulated to make a shallow furrow which the front disk will deepen and widen during the next operation, while I "the rear, disk makes another shallow furrow.

It is obvious. that the various operations and regulations of the disks, as just described, will vary the tendency to turn the" frame to one side or the other, andas such tendency is counteracted bythe position of th .iurfow wheel at, the special steering means involvingthe hand-leverlt) and its connection with the'steering wheel enter into combination with the variableness of the disks' o'r plowing means, to enable the disks inonnted one directly rearward 'of the other on the frame, said rear disk being -movable on the frame from a position directly rearward of the front disk, to a pos tion in which it may make a second furrow; said rear disk being also adjustable verti cally on the frame, for the purposes set forth.

2. Ina'disk plow, the combination with a frame and wheels supporting it, of two disks mounted on the frame onedirectly rearward of theother, said rear disk being adjustable vertically and to different oblique directions on the frame and movable from a position directly rearward of the front disk "to a position in-which it makes a second fur-row.
